How to distinguish IC card intelligent water meter can demand transformation batteries?

Source: 2020 - 03 - 25 choicest hits: time how to identify whether the IC card intelligent water meter need to transform the battery: 1. Not the electronic flash on the water meter in the local flicker meter, water meter sends out alarm, illustrate the meter battery is low, the meter battery needs to be replaced. 2. When runs out of water meter, water meter did not close the valve, causing the water to flow out from the water meter, this kind of circumstance is the meter batteries. 3 found that water meter counts are not accurate, can be water meter a dead battery, may be the IC card intelligent water meter is broken. 4. Low voltage testing: when the battery voltage is lower than 3. , 8 v motor, the valve closed 'under-voltage' and 'close the valve. This will need to install a new battery to back the use of IC card water meter. How to change the water meter battery: 1. Open the battery box seal, remove the hatch cover screw, remove the batteries. At the bottom of battery box in the instrument. 2. Press the snap ring, unplug the connector, disconnect the battery snap ring. Water meter by 2 to 3 v lithium battery, CR14505E type 2 series, battery connected to the meter by card buckle. 3, battery, can be purchased from the taobao search 'CR14505E' can, price is about 30 - 40 yuan. 4. After buy new battery, pay attention to the positive and negative is the same as the primary element, main cables. If correct, use water meter buckle ring insert card. How long is the use of intelligent water meter battery? General water meter manufacturers committed to the battery life is 3 - smart meters Six years, but this number is how to? Intelligent water meter in everyday use, the power consumption of concentrated mainly has the following several aspects: the battery self-discharge consumption, consumption valve switch, magnetic card communication consumption, LCD flash consumption. Current meter module of constant current are under 3 ua, total energy consumption of about 970 ma (6 years About 80 ma / 9 s) valve switch traffic 。 This is just a theoretical value, there is no any questions cannot be estimated. Assume that pipe network under pressure, 0. 4mpa) General requirements of switch valve current is more than 90 ma. The total capacity of the battery life is not the practical value, generally the best battery capacity is 80% of the battery. As applied to the later period, increase resistance, power consumption is also increased. Manufacturer of general use lithium battery capacity is 2000 mah, more actual power consumption of about 1200 - 1300 mah, based on the differences of the quality of the water meter and user usage has the very big difference, in the 3 - 6 years and more common. Intelligent water meter to improve our condition, not only saves manpower, water is no longer bother, for us and provides us with water and capture to expend bento, saving water is beneficial to us. It is a water meter need battery, battery belong to power consumption, no matter what kind of battery, will be no electric power, this is about us to pay attention to the power consumption of the battery, no electricity transformation ahead of time. Have many kinds of water meter, we are optimistic that our water meter can be converted into the battery in accordance with the method of fixed varieties.
